UNITED STATES ROBERT SCHILLER, OF CHICAGO, ILLINOIS.

WINDOVV-WASI-IERS SEAT.

Application filed September 16, 1921. Serial No. 501,089.

To aZZ whom it may concern Be it known that I, Ronnn'r SCHILLER, acitizen of the United States, and a resident of Chicago, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in VindmwVVashers Seats, of which the following is a full,clear and exact description.

My invention relates to a seat structure to be applied on the sills ofwindows to support persons while washing the outside of the windows. i

One of the important objects of my in vention is to provide a simple,practical and efficient structure which is adjustable to accommodateitself to windows of different Another important object is to provide astructure which can be folded into small space when not in use. Anotherobject is to make the structure light so that it can be readily carried,but at the sametime to make it strong and safe;

The above and other features of my invention are incorporated in thestructure shown on the accompanying drawing, in whichr Fig. 1 is aperspective View of my improved seat structure in unfolded positionready for application to a window sill and led e,

ig. 2 shows the device folded up,

Fig. 3 is a side elevational view showing the structure in place readyfor use,

Fig. 41: is a plan View of the structure shown in Fig. ,3, and

Fig. 5 is a fragmentary view showing a modified arrangement.

The device comprises a back 10 which may be of sheet metal. andreenforced along its side edges by angle bars 11.. Hinged to the back byhinges 12 and near the lower edge of the back is the seat board 13 whichmay also be of sheet metal suitably reenforced along its side edges byangle bars lat. Hinged to the back 10 near the upper corners thereof byhinges 15 are the side structures16 and 17 in the form of lazy-tongsframes built up of the bars 18 pivoted together. Each frame is securedby its realbar 18 to the hinge 15, the sides being thus extensiblelongitudinally. The front bar 18 of each side frame terminates at itslower end in a hook 19.

In Fig. 3 1 show the device applied to a window structure. The books 19are engaged around the inner edge of the inner 11, a row of slots 525being provided in each,

strut bar to provide for adjustment. Also after application of the seatthe lazy-tongs side frames are rigidly locked against expansion orcontraction by means of the lock bars 26 which are pivoted at the upperends of the respective rear barslta of the frame and at their outer endshave the notches 27 for receiving button heads 28 provided on Afterapplication to the sill board the pivot pins which connect together theframe bars intermediate their ends; The seat structure isnow rigidlyheld to the window structure and a person can comfortably sit on theseatboard and supported by the back 10, be in convenient position forwashing the windows on the outside.

If the sill board and ledge board do not afford suflicient width forcomfortable sit-- ting, then the seat board is shifted outwardly asindicated in dotted lines in Fig.

3 tobring the back away from the outer edge of the ledge. The strut bars"22 and 23 and the lock bars 26 are then applied to rigidly lock thestructure against collapse. tensible and adjustable for different widthsofwindow structures and when thebrace bars and locking bars are appliedthe structure is strong and rigid and can be used with comfort andsafety.

When the device is not in use the seat board is foldedup against theback board and the lazy-tongs frames are contracted and swung inwardlyagainst the seat and The structure is thus readily exbackboard asindicated in Fig. 2. The

strut bars are swung into a position parallel with the angle bars 1 1and the lock bars will hang down in front of and parallel with the seatboard. When the device is thus folded up it is very compact and occupieslittle space and can be easily transported, packed, and shipped.

In Fig. 5 I have shown a modified arr21 ugen'ient for locking thelazy-tongs frames. Instead of providing slots in the lock bars 29 Iprovide a single longitudinal slot 30 which receives the pivot pins 31of the frame bars, these pins being threaded at their outer ends toreceive the wing nuts b2. After setting of the device in place the wingnuts are screwed down to rigidly clamp the locking bars and thus lockthe frame against expansion or contraction.

I do not desire to be restricted to the details set forth, as these maybe modified within the scope of the appended claims, without departingfrom the spirit andv scope of the invention.

I claim as my invention:

1. In a window washers seat, the combination of a back, means forsupporting said back on a window ledge, lazy-tongs structnres extendingforwardly from said back and means for detachably securing the ends ofsaid structures to a window sill.

2. In a window washers seat, the combination of a back, means forsupporting said back on' a window ledge, lazy-tongs structures extendingforwardly from said back, means for securing the ends of said structuresto a window sill, and means for looking the structures in more or lessextended positions.

3. A detachable seat structure for window frames comprising a back, sidearm struc tures in the form of lazy-tongs extending forwardly from saidback, means for supporting said back on the ledge of the window frame,and hooks at the front ends of said side structures for engaging aroundthe inneredge of the window sill.

4:. In a window frame seat attachment, the combination of aback, meansfor supporting said back on the outer edge of a window frame,longitudinally foldable side arm structures extending forwardly fromsaid back, means at the outer ends of said arms for engaging with theinner sill board of the window frame, said arms'being hinged to saidback whereby when folded up they may be swung against said back.

5. In a seat attachment for window frames, the combination of a back,means on said back for supporting it on the outer ledge of the windowframe, side arm structures extending forwardly from said back, hooks atthe front ends of said side arm structures for engaging around the inneredge of the inner sill board, said side arm structures being foldablelongitudinally and hingedto said back whereby after folding they'may beswung against said back.

6. In a seat attachment for window frames, the combination. of a back,means at the lower end of said back for supporting it on the outer ledgeof a frame, side arm structures. in the form of lazy-tongs extendingfrom said back, meansat the outer ends of said side arm structures forsecuring them to the inner sill board of the frame, locking mechanismfor locking said lazy-tongs in expanded position, said lazy-tongs beinghinged to said back whereby when they are folded up longitudinally theymay be swung against theback.

7. In a window washing detachable seat for window frames, thecombination of a back, a seat board hinged to said back near the loweredge thereof and adapted to be folded against said back, strut bars forbold ing said seat in fixed position away from said back, said seatbeing adapted to rest on the ledge of a window ti rame, adjustable sidearm structures extending. from said back, means at the outer ends ofsaid side arm structures for engaging with the inner win dow sill of thefran'ie, said side arm structures being hinged to the back to be foldedagainst the back when the device is not in use.

10. In a window washing detachable seat structure for window frames, thecombination of a back board and a seat board hinged together, means forlockingsaid boards in open position with said seat board resting on theledge of a window frame and the back board held in upright position,side arm structures in the form of lazy-tongs hinged to said back board,hooks at the front ends of said sidearm structures for engaging aroundthe inner edge of the inner sill oi" the Window frame, and lock bars forsaid side arm structures for securing them to the inner sill board of aWindow frame, and locking bars adapted to engage With the ba ot thelazy-tongs frames to prevent re lative movement thereo't whereby saidframeswhen expanded are locked against contraction. c 12.111 adetachable seat for Window frames, the combination of a baclgnmeans forsupporting said back at theouter edge of the ledge of a Window frame,lazy-tongs extending from said back near the sides thereof, hooks at thefront ends of said lazytongs for engaging around the inner edge of theinner sill board of the frame, and means for locking the bars of saidlazy-tongs frames against relative movement to thereby rigidly lock saidframe.

In Witness whereof, I hereunto subscribe my name this 9th day ofSeptember A. 1)., 1921.
